What Are the Experiences of Emotional Labor and Workplace Violence that Are More Harmful to Health in Korean Workforce?

The Potential Relationship Between a Cognitive Dissonance State and Musculoskeletal Injury: A Systematic Review

OBJECTIVE

The objective of this systematic review was to investigate the potential link between cognitive dissonance or its related constructs (emotional dissonance, emotional labor) and musculoskeletal disorders.

BACKGROUND

The etiology of musculoskeletal disorders is complex, as pain arises from complex interactions among physical, social, and psychological stressors. It is possible that the psychological factor of cognitive dissonance may contribute to the etiology and/or maintenance of musculoskeletal disorders.

METHOD

MEDLINE, APA PsycInfo, and CINAHL Plus databases were searched for studies investigating cognitive dissonance or its related constructs as exposure(s) of interest and outcomes related to physical health (including, but not limited to, musculoskeletal pain). Risk of bias was assessed using the Appraisal tool for Cross-Sectional Studies (AXIS) tool.

RESULTS

The literature search yielded 7 studies eligible for inclusion. None of the included studies investigated cognitive dissonance directly but instead investigated dissonance-related constructs of emotional dissonance and emotional labor, in which a mismatch between required and felt emotions might elicit a psychological response consistent with the cognitive dissonance state. Moderate effect sizes between dissonance-related constructs and musculoskeletal disorders were noted (OR 1.25-2.22).

CONCLUSION

There is likely a relationship between the two factors studied. However, as the included studies were cross-sectional in nature, a causal relationship between cognitive dissonance-related constructs and musculoskeletal disorders cannot be inferred. Therefore, future study proposing and validating a causal pathway between these variables is warranted.

APPLICATION

Cognitive dissonance and its related constructs may serve as risk factors for musculoskeletal disorders that have not been considered previously.

Reliability of FUNDES-Child-SE - measuring participation and independence of children and youths with disabilities

BACKGROUND

There is a need for an instrument to measure participation and independence in children with disabilities. FUNDES-Child-SE has its origin in the participation questionnaire Child and Adolescent Scale of Participation.

AIMS

Test the psychometric properties of internal consistency and test-retest reliability.

MATERIAL AND METHODS

This cross-sectional study included caregivers of 163 children with disability aged 6-18 years, 59 of whom were also included in the test-retest study. Descriptive statistics were used to evaluate the proportions of valid ratings. Internal consistency and test-retest reliability were tested through Cronbach's alpha and the intra-class correlation coefficient.

RESULTS

The amount of not relevant/not applicable ratings was substantial but varied between items and subdomains. Internal consistency was acceptable (0.8-0.95), and the test-retest was marginal to excellent (0.73-0.95).

CONCLUSIONS

The reliability together with the content validity support the use of the FUNDES-Child-SE to measure participation and independence in children with disabilities. However, results should be interpreted with caution due to the small sample size and possible selection bias. Modifications to reduce the not relevant/not applicable responses should be investigated together with the instrument's responsiveness.

SIGNIFICANCE

FUNDES-Child-SE can be used to facilitate a discussion of participation and independence and to plan interventions in a habilitation setting.

Associations Between Workplace Violence and Mental Health Among Chinese Health Technicians: A Moderated Mediation Analysis of Sleep Quality and Physical Activity

Background

Workplace violence (WPV) had always been the focus of attention in all walks of lives, especially in the health fields. Previous studies had shown it adversely affected mental health for healthcare workers. In addition, both sleep quality and physical activity were supported to have impact on mental health. However, the mechanism of sleep quality and physical activity influence the association between WPV and mental health had not been explored, so the purpose of this paper was to explore this mechanistic link among workplace violence, sleep quality, physical activity, and mental health in Chinese health technicians.

Methods

Cross-sectional study was conducted in 3 cities of China, totally 3426 valid questionnaires were collected. WPV, physical activity, and social-demographic variables were evaluated. The Pittsburgh Sleep Quality Index and the Kessler Psychological Distress Scale were used to measure sleep quality and mental health. Descriptive analysis, univariate analysis, Pearson correlation, and moderated mediation analysis were used to estimate prevalence of WPV, association between WPV and mental health, and the role of sleep quality and physical activity on association between WPV and mental health.

Results

The prevalence of WPV was 52.2% among Chinese health technicians. After controlling social-demographic and work-related variables, sleep quality partially mediated the effect of WPV on mental health (indirect effect=0.829). Physical activity moderated the relationship between WPV and sleep quality (β=0.235, p=0.013), but not find the moderating role between WPV and mental health (β=0.140, p=0.474), and between sleep quality and mental health (β=0.018, p=0.550).

Conclusion

The rate of WPV among health technicians remained at an alarming level. Sleep quality and physical activity could mitigate the adverse effect of WPV on mental health. In the future, we could improve sleep quality and encourage health technicians to engage physical activity to decrease the negative effect of WPV on mental health.

Associations Between Workplace Violence, Mental Health, and Physical Health among Korean Workers: The Fifth Korean Working Conditions Survey

BACKGROUND

Workplace violence (WPV) is a global public health problem and a threat to the health of Korean workers. This study assessed the prevalence and risk factors of WPV and its association with mental and physical health among Korean workers.

METHODS

Data obtained for 50,205 respondents to the Fifth Korean Working Conditions Survey were utilized for this study. Verbal abuse, threats, physical violence, and sexual harassment were assessed individually and as a composite for "any WPV." Workers were characterized by education, income, shift work status, access to a health and safety education program, work sector and overall health. Descriptive analyses and multiple logistic regression analyses were used to estimate the prevalence of WPV and its association with mental and physical health.

FINDINGS

Overall, 5.6% of workers reported experiencing one of four forms of WPV. The prevalence of verbal abuse, threats, physical violence, and sexual harassment were 4.9%, 0.7%, 0.2%, and 1.1%, respectively. Most perpetrators were customers. Prevalence of WPV was associated with lower education level, poor health status, long working hours, shift work, and no experience of health and safety education; 9.0% of service workers experienced violence. Workers who had experienced WPV were more likely to experience anxiety, sleep-related problems, depressive symptoms, back pain, headache/eye strain, and overall fatigue.

CONCLUSIONS/APPLICATIONS TO PRACTICE

Workplace violence is a serious occupational and public health concern in Korea. These results suggest managing WPV may improve workers' well-being and that violence-prevention strategies, policies, and regulations should be implemented across most industries.
